tially heating the burner, such burner being.

usually equipped with a generator tube. The primary object of thisinvention is toprovide a 'novel form of apparatus which is soconstructed that it may be connected or positioned within a gasolinetank and supply gas,

'. that is to say, carbureted air, "adapted to be lighted by a matchwith the same facility as an ordinary gas burner, and which, after it islighted, will draw a richer mixture'from the apparatus and heat theburner, and also-light it, thereby avoiding all danger of spilling orflooding, which has heretofore existed in the gasoline burners asusually constructed.

Further objects of this invention are to provide a device which isextremely simple, which has a relatively small number of easily produced parts and which is easily insertible within a gasoline'supplytank.

An embodiment of the invention is shown in the accompanying drawing, inwhich The single figure is a view somewhat dia-' gralnmatic, showing insection a portion of the tank and apparatus connected thereto.

Referring, to the drawing, it will-be seen that the gasoline supplytankis indicated by the reference character 1, and it is usual to fillthese tanks to approximately between the level indicated at 2 and 2. Thegasoline tank is provided with an aperture, through which a-sleeve 3 isinserted, such sleeve being closed at its upper end by means of aflanged head 4, and closed at its lower end by means of the head 5. Thesleeve is preferably inset with reference to the cylindrical surface ofthe head 4, so that it will be flush with such cylindrical surface tothereby facilitate the initial insertion of the tube. This head iswelded,"brazed or otherwise secured to the tank and to the sleeve 3.Similar processes may be employed for securing the head 5 in place,although, obviously, other processes or other means could be used. Thehead 4 is provided with a fitting 7 screwed thereto and communicatingwith the upwardly converging openingf8. This fitting communicates withthe, pi e 9Vwhichleads-tof'theqdischarge, tube 1O. bommunicationwithfthe discharge tube is controlled by the valve 11. ,If desired, thetube 9 maybe flexible, so that the device can be used for'any of severalburners.

It also may be rigid, as shownin the drawing,

and the tube 10 may be positioned above a cup 12. The burner is notshown in the drawing, as the construction is well-lmown. f

WVithin the tube 3, a smaller central tube 13 is positioned, and opensat its upper, end 7 into the passageway 8. At its lower end it iscarried by a reduced portion 14 of the head 5, and is provided adjacentsuch, lower end with apertures 15. The tube '13 is contractedintermediate its ends, as shown atl6, to form a Venturi tube! Within thetube13 a smaller fuel tube,por nozzle 17 is positionedfancl opens at itsbottom end through the headfi,

The upperend of the nozzle is positioned in the Venturi tube, or portion16; The upper portion of the tube 3 is provided with a p'lurality ofapertures 18, located above the liquid'level2. f

In operation, the air under pressure in the upp er'portion of the'tankpasses downwardly through the openings 18, enters the tube 13through theopenings 15, passes upwardly, and whenthe valve 11 is open,passes outwardly through the discharge, or ignition; pipe 10. Duringthis passage, the somewhat enriched air in the upper portion of the tankis additionally, enriched due; to .the suction produced in the top ofthe nozzle 17, so that after a few seconds, a relatively rich mixture isdischarged from the pipe 10. The resulting flame from the pipelO is usedto heat the burner and generator tube (not shown), and after suflicientheating, is used to light the burner, when theburner is turned on.

It is apparent that a lessening of the danger of fire over theusual formof priming cup construction is provided by this volatile fuel lighter;there is no liquid gasoline discharged by the apparatus. Instead, theburner may be lighted with the same facility as ordinary gas. Inaddition to this, this mixture is relatively thin at starting and dangerfrom'fire is reduced, and after a few seconds the flow then becomesricher and ives, consequently, more heat at the flame. Clearly, thisapparatus may be provided with a flexible pipe in the place of pipe 9,if desired, so that any number of burners may be heated and lighted witha single apparatus.

Attention is directed to the fact that the normal liquid level withinthe pipe 17 or nozzle, is at'a point intermediate its ends, consemquently, the solid stream of fuel cannot flow through the pipe 17, thuseliminating the danger of flooding. 7

It will be seen that a very simple and highly serviceable device hasbeen provided a by this invention, which is easy to operate and whichmay be cheaply constructed. a

,While the expression gasoline is used in the claim, it to be.understood that this expression is not intended as a limitation, as

any suitable volatile fuel may be employed.

Although the invention has been described in considerable detail, suchdescription is intended as illustrative rather than limiting, astheinvention may be variously embodied.

and as the scope of such invention is to be determined as claimed.

We claim:

A volatile fuel lighter for a gasoline stove having a tank adapted tocontain gasoline,

a fitting extending into the upper portion ofsaid tank, a sleeve carriedby said fitting, and projecting downwardly into said tank below the fuellevel and having openings above the fuel level, a lower head. closingthe bottom of said sleeve, a nozzle passing through said lower head andprojecting upwardly Within said sleeve, a tube located within saidsleeve and surrounding said nozzle and having a constricted portionadjacent the upper end of said nozzle and opening adjacent its lower endinto the space within said sleeve, and a pipe communicating with theupper end of'said tube, said pipe being provided with a cut-off valve.

5 In testimony that we claim the foregoing we have hereunto set ourhands at Milwaukee, in the county of Milwaukee and State of Wisconsin.
